Roof drain DN40/50 with horizontal outlet, siphon PRIMUS, plastic collar 34-78mm, frame 150x150mm and cast iron grate 137x137mm HL510PRBLUEG

Primus floor drain with dry siphon – reliable drainage

This floor drain, with a DN40/50 drain diameter and horizontal outlet, is a solid solution for draining water from ceiling surfaces. Equipped with the innovative Primus siphon, it effectively blocks unpleasant odors, even when the water in the siphon completely evaporates – which is especially important in rarely used rooms or seasonal buildings.

Construction and installation

The drain is characterized by a well-thought-out design, enabling easy and tight installation. The drain collar allows integration with the waterproofing layer using dedicated HL83 sealing kits, guaranteeing safety and durability of the connection. The adjustable riser made of plastic (range 34-78mm) and a frame with dimensions of 150x150mm allow adaptation to different ceiling layer thicknesses. The drain grate made of cast iron (137x137mm) ensures strength and resistance to loads – up to 1.5 tons.

Application and benefits

• Primus dry siphon: Eliminates unpleasant odors even without water in the siphon – an ideal solution for occasionally used rooms.

• Tightness: The possibility of a tight connection with the waterproofing layer minimizes the risk of leaks and structural damage.

• Versatility: Thanks to the adjustable riser height and the use of additional elements (HL340N, HL85N, HL85NC, HL85NH), the drain can be adapted to different ceiling layer configurations.

• Durability: The cast iron drain grate provides high resistance to mechanical loads and long-term use.

• Efficiency: A flow rate of 0.55 l/s ensures efficient water drainage.

• Thermal resistance: The materials used in production exhibit resistance to temperatures up to 85°C.

This drain is an optimal choice for both professional installers looking for a reliable solution and end customers who value comfort and safety. Its solid construction and well-thought-out solutions guarantee long-lasting and trouble-free operation.
